2in 1 Rechargeable Helmet Light with Bracket Mount Night Bike Light Riding Safety 5 Warning Light Modes IP66 Waterproof Bicycle Light, 360° Rotatable Front Rear Lights, Mountain Bike Headlight

Pro's:1. Insanely bright for such a small light. I bought this so that I would be visible. I didn't expect to be lighting up reflective STOP signs from 50 yards away! Blinding pedestrians!! 2) Was worried about installing on my helmet but it was a breeze. Straps go through the air vents on top of the helmet. If you have a solid helmet you might want to check on other mounting options. I didn't look. 3) multiple modes - solid spot light to flashing work great for visibility.Con: be careful with the added height of your headgear. You don't realize how high the light sticks up if you go under a tree limb. I learned the hard way. My light got knocked silly but survived and is still working fine.Don't Know: Haven't used it long enough to comment on battery life, but you can leave the mount on the helmet and just pop off the actual light for recharging the battery. Easy peasy. I have ridden about thirty miles and haven't recharged yet. No signs of battery depletion or need for recharge,

Easy to attach to my helmet, easy to charge, and super bright. Definitely recommend for an added layer of visibility

Context: purchased end of July, 2024, to prepare for twice weekly bike commute trips, 24 miles a day through a mix of country and city streets. Thus far rode about 30 hours or 450 miles.Overall, this is a pretty good little helmet light. The plusses are: the purchase price was very reasonable, i.e. Inexpensive, mounting to helmet was simple enough, the lights are bright.The minor gripes are: the unit is surprisingly tiny. Seems like a lot of light for the size and weight. But it also means a small battery. I think I charged it 3 or 4 times. So 10 hrs of fun time isn't exactly bad, but the way it went dead isn't good. I would turn on both the front n read light before I start my ride in the morning. And it would be off when I arrived. That means I do not know how long I was riding without light. And the it will allow me to turn on again. The charging time exceeds 2 hours I think. And as mentioned by others, there is no indication the charge level is low.I do not recommend to use this helmet light as your only bike commute light, since you cannot know exactly when it will cut out. But add a good tail light, like a Night Rider, then you are covered.

This thing is seriously bright. I’ve seen car headlights that aren’t this bright. The battery will last a long time between charges. It is phenomenal.

Holds a charge for at least 2 hours and mounted easily onto bike helmet

I ordered this item in June. It was great when I first received and started using it. Now have been using it for 2 months and it will not hold a charge for an entire 1.5 hour ride. I only ride 3-4 times a week.I gave it one star because I couldn't give it zero stars.

Super light,charges quickly and lasts for ages on a single charge. Various strobe sequences for the front and back lights, each can be set differently and can be set to stay on light a regular flashlight. Very light weight and mounts to the same fittings that my GoPro uses. At $15 or so it's a real deal.

If you are like me and have one of the Bontrager Bike helmets with the WaveCel technology, then know this light will NOT work with your helmet. It uses a strap to attach that uses velcro to secure itself underneath the helmet. The WaveCel prevents you from being able to access the strap. Make sure you have the ability to access any kind of strap inside your helmet that you feed from the top (or outside) of your helmet before purchasing. Of course, Amazon was great and allowed me to return the unused light.
